Her goal for each of our patients is to not only have a wonderful “dental” experience while at our office, but to make the business aspect of dental care a pleasant one.

Kim Dornan Hygienist

Kim Dornan

Kim has been working in dentistry since 1981. She began her career as a dental assistant. After many years as an assistant, she began working in the front office as needed and began taking night time college courses. Kim earned my first degree in computer programming.

After years of managing a large periodontal practice in Southern California, Kim decided she needed a change of life, so she moved to the Bitterroot Valley, began taking a couple of needed science classes from U of M and then applied to hygiene school. Kim graduated with a 4.0 and a degree in Dental Hygiene fall of 2007.

Kim has been working for Dr. Andy Kehmeier since September 2009. Her goal as a dental hygienist in Dr. Kehmeier’s practice is to provide our patients with the treatment they need in a gentle and caring manner. She takes pride in her ability to communicate with her patients regarding their oral home care needs. If there is anything Kim can do to make your home care easier, please let her know.

Betty’s first real job right out of high school was for an oral surgeon by the name of Dr JP Slaughter as a surgical assistant. That job set her on the path of working in the dental field. Betty moved to Hamilton in 1994, and in 1995 she started her career at Dr Kehmeier’s office.  She really enjoy interacting with the patients and being a part of the transformation of smiles.

Betty spends her spare time hanging out with her grandchildren, all 7 of them now, and riding her horses in the mountains.
